不同体质指数直肠癌患者腹腔镜根治术后疗效比较

目的探讨不同体质指数的直肠癌患者行腹腔镜根治术的安全性及对生存率的影响。方法选择2008年1月~2012年12月行腹腔镜直肠癌根治手术的患者共86例,按照体质指数划分标准分为三组:体重正常组37例,超重组31例,肥胖组18例。比较三组患者的术中情况、术后恢复及并发症及近期生存率等情况。结果三组患者术中出血量、淋巴结清扫数、肛门排气时间、术后住院时间以及术后并发症发生率比较差异均无统计学意义(P0.05),但肥胖组手术时间长于其余两组,差异具有统计学意义(P0.05)。随访79例,中位生存时间为22个月,三组生存曲线比较差异无统计学意义(P0.05)。结论患者的不同体质指数不影响行腹腔镜下直肠癌根治术的疗效、安全性及近期生存时间。

Effect Comparison of Laparoscopic Radical Rectectomy of Rectal Cancer among the Patients with Different Body Mass Index

Objective To explore the safety and survival rate in rectal cancer patients with different body mass index （BMI） undergoing laparoscopic radical resection of rectal carcinoma. Methods A total of 86 rectal cancer patients undergoing laparoscopic radical resection of rectal carcinoma from January 2008 to December 2012 were divided into three groups according to their BMI, including normal weight group （37 cases）, overweight group （31 cases） and obese group （18 cases）. The general information, intra-operative status, post-operative complication and recovery and short-term survival rates were compared among those three groups. Results There were no statistic difference in intra-operative blood loss, numbers of lymph node dissection, ex- hausting time, postoperative hospital stay and the incidence of postoperative complications among those three groups （P 〉 0.05, respectively）. But the operation time of obese group was significantly longer than that of the other two groups, there was statistic difference （ P 〈 0.05 ）. 79 patients were followed up with a median survival time of 22 months. There was no significant difference in survival rate among three groups （P 〉 0.05）. Conclusion BMI does not influence the efficacy, safety and short-term survival of the rectal cancer patients undergoing laparoscopic radical rectectomy.
